Dial belts again

[lurch]

Has anyone thought of using miniature toothed rubber belts, commonly
known as Gilmer belts?  I'm just a lurker on this list, don't own any
greenboxes at the moment, but I have seen Gilmer belts in sizes all the
way down to 1/4" wide.  I think McMaster-Carr carries the belts and
pulleys, as well as miniature chain and the associated sprockets...

"It is sadly typical of a decayed society that the majority
are willing- without question and damning those who do question-
to follow any authority figure,
selling their birthrights and betraying their neighbors,
all for the promise of temporary relief of some problem.
I'm sure you remember what Benjamin Franklin
had to say about such a people."
